Question

嘿，我正在寻找一种智能且简单的方法来将 Pandas 中的 2 列从另一个数据框中连接成一个新的列。我的旧数据框看起来像：

<头>

姓名1	name2	name3
汤姆	爱丽丝	鲍勃
汤姆	丽莎	最大
爱丽丝	劳拉	鲍勃

新数据框只有 2 列 (A,B)。我想比较新数据框中旧数据框中的每一列，例如：name1 & name2，在 name1 & name3 之后，至少 name2 & name3

Answer 1

我找到了一个简单又好用的方法。这个有效：

  <g id="Group_1" data-name="Group 1" transform="translate(-1011 -176)">
